I wonder if this is a Lepista nuda.

I originally thought Aprica straight away when I saw it and commented so above - but then kind of talked myself out of it on second inspection, because I couldn’t see any remnants of their distinctive universal veil on the cap.

I find it so fascinating that muscarias have such colour variations over there, where I am in Europe they are all deep, deep red. Only once have I seen a dark orange one. The light shades are lovely specimens.

Edit: actually, I take back my first statement. I think the white ring consistently around the rim is indeed what’s left of a singular veil, and that points to Amanita aprica.

In North America there is a variant of muscaria found called guesowii, that is known colloquially as the American Yellow Fly Agaric. Also, muscaria can come into season in late summer in that region, whereas in Europe we do not see them until autumn is in full swing at least. If this was found early summer I would consider a different amanita ID to a muscaria as possibly a bit too early :)

In that case, I am torn between the Amanita muscaria variant guessowii, or possibly even an Amanita chrysoblema. Absolutely stunning find either way. We very rarely get the yellow variants of muscaria in my locale, they are beautiful. Thanks for the picture :)

I actually think this is an Amanita aprica, or the Sunshine Amanita. But it is sometimes possible to find muscarias that are paler than their usual distinctive red.

The way to know for certain would be checking what time of year you found it, where you found it, and what kind of tree and habitat it was in.
